  • Biostratigraphic and paleoenvironmental analyses are carried out on cutting samples from the Dolgorae wells drilled in the Ulleung basin. The clayey, silty, and sandy sediments of the wells yield various microfossil assemblages of relatively good preservation, among which five fossil groups are reported; a total of 97 foraminiferal species of 66 genera, 19 nannofossil species of 12 genera, 86 ostracod species of 41 genera, 107 diatom species of 44 genera, and 124 dinoflagellate cysts species of 45 genera. Based on microfossils the geologic ages of the Dolgorae wells are dated to be from late Early Miocene to Early Pleistocene. Several biohorizons are defined in Neogene successions by the LOD (Last Ocurrence Datum) and FOD (First Ocurrence Datum) of marker species including G. truncatulinoides (LOD: 1.9 Ma) of foraminifera; C. macintyeri (LOD: 1.64-1.60), G. oceanica (FOD: 1.65 Ma), G. caribbeanica (1.72 Ma), D. brouweri (LOD: 2 Ma), R. pseudoumbilica (LOD: 3.66 Ma), P. lacunosa (FOD: 4.2 Ma) of nannofossils; S. ellipsoideus (LOD: 4 Ma), S. palcacantha (LOD: 10.2), C. giusepei (LOD: 14 Ma) of dinocysts; D. seminae v. fossilis (FOD: 3.7 Ma), T. antiqua (LOD: 1.7 Ma), T. convexa (LOD: 2.4 Ma), N. kamtschatica (LOD: 2.58 Ma), T. oestrupii(FOD: 5.1 Ma) of diatoms. Abundance patterns of microfossils throughout the wells reflect changes in paleoenvironmental and sedimentological settings of the basin in relation to sea-level variations. According to these data the large-cycle and small-cycle changes of transgression and regression phases are observed in terrestrial to marine sediments. This high-resolution sequence biostratigraphy established by various fossil groups enabled more reliable correlation between strata and refined interpretation on deposition systems of the basin. It also proved to provide fundamental and precise informations regarding stratigraphic correlation, tectonic events, basin, and depositional history for hydrocarbon explorations, especially in collaboration with seismic-stratigrahic analyses.

  • The depositional environment of the Manhang and the Geumcheon Formation of the Pennsylvanian Gomog Croup is revealed to the shallow neritic marine milieu in this paper also as the results of Park (1963), Cheong(1975) and Kim (1976), through the analyses of stratigraphy, paleocurrent, properties of cross-beddings and sedimentational features. The formations contains some possible terrestrial sediments suggesting the paralic environment, which are however not recognized definitely within them. The paleocurrent analysis is made to the Manhang Formation only. The paleocurrent of the formation is known to belong to the shallow neritic longshore current. The paleocurrent analysis is based chiefly on the cross-bedding analysis, and subordinately on the texture of elastic coarse sediments. The paleocurrent mean is determined to $269^{\circ}$, that is, from east to west, of which direction is interpreted to the right angle to the slope of the basinal depository plane and also the parallel with die depositional strike, according to Klein (1960) and Selley's (1968) criteria. The variance value of paleocurrent directions of the Manhang Formation in the whole area studied is 6,374, and the values range from 3,394 to 6,957 according to the dirstricts. The paleocurreut pattern of the whole area shows polymodel, and the patterns in each district range from trimodel to quadrimodel. Those models approach to the shallow marine or paralic model of Tohill and Picard (1966), Picard and High (1968 a), Pisnak (1957) and Pettijohn (1962). The mean value of maximum inclinations of cross-beddings of the whole area is $19.9^{\circ}$ with the standard deviation of 8.4, and ranges from $15.6^{\circ}$ to $21.7^{\circ}$ in the districts. Comparing the histogram showing the frequency distribution of the maximum inclinations of cross-beddings of the Manhang Formation with the Pettijohn's (1962) histogram, it is found that the model approaches to his marine model. The Pennsylvanian Gomog Group of the coalfield is considered to have had been deposited in the pseudogeosynclinal zone on the plateau by the transgression of the Tethyan sea caused by the epirogenic movements during the Pennsylvanian Period.

  • The space of the Other assumes the space of Barthes's multiplicity and Foucault's transdiscursive position, and, therefore, aims at becoming the locus in which the speaking subject and the hearing subjects are supposed to communicate and constitute as if they were situated in the pscychoanalytic session. However, the wall of untranslatibility across language and cultures still exist there in the space of the Other in the form of trauma and aggressivity, as Lacan demonstrate perceptively through the reading of Kant avec Sade. In short, Lacan regards the moral commandment (to love one's neighbor as oneself) as the obstacle in the Freud's myth of transgression, and interprets this in terms of the emergence of the Other. Freud understands that the aggressivity in the subject's own heart was inherent in all humans, and that one's neighbor would be evil. Lacan goes beyond Freud and articulates that the aggressivity in the imaginary relation with the Other in the mirror stage insures that an evil inheres in the very being of humanity. A global phenomenon of the diasporic identities and hybridity, the phenomenon which has been represented by the complicated intermixture of terms which span from diaspora, postcolonialism, postnationalism. and transnationalism can be clarified, if they are put in the context of the ethics of Othering or becoming the Other. The ethics of Othering presupposes the situation in which the diasporic subjects encounter the lack of the cross-cultural negotiation and communication. The purpose of this paper is to demonstrate how the poetics of Other and the logic of the ethics of Othering can explain the postmodern or transmodern world which has become deterritorialized, diasporic, and transnational as well as how one can encounter the results of diasporic and postcolonial double consciousness, a consciousness which is a discursive category for multicultural or cross-cultural, focusing on the concept of liminality/interstitiality

  • Objectives: The outcomes of the treatment of unilateral cleft lip can vary considerably due to variations in repair techniques. The aim of this study was to evaluate and compare treatment outcomes of surgical repair of unilateral cleft lip using either the Tennison-Randall or Millard technique based on (qualitative) parent/subject and professional assessments. Materials and Methods: This was a prospective, randomized, controlled study conducted at Lagos University Teaching Hospital between January 2013 and July 2014. A total of 56 subjects with unilateral cleft lip presenting for primary surgery who satisfied the inclusion criteria were recruited for the study. Subjects were randomly allocated to surgical groups A or B through balloting. Group A underwent cleft repair with the Tennison-Randall technique, while group B underwent cleft repair with the Millard rotation advancement technique. Surgical outcome was assessed using qualitative evaluation by the guardian/subject and independent assessors based on a modified form of the criteria described by Christofides and colleagues. Results: Of the 56 subjects enrolled in this study, 32 were male, with a male to female ratio of 1.3:1. Fifteen of the guardians/subjects in the Tennison-Randall group were most bothered about the lower part of the residual lip scar, while 12 guardians/subjects in the in the Millard group were most bothered about the upper part of the scar. More noses were judged to be flattened in the Millard group than in the Tennison-Randall group. Assessors observed a striking disparity in scar transgression of the philtral ridges between the two groups. Conclusion: Essentially, there were no major difference in the overall results between Millard rotation-advancement and Tennison-Randall repairs. Both Millard and Tennison-Randall's techniques require significant improvements to improve the appearance of the scar on the upper part and lower part of the lip, respectively.

  • Heterogeneous sedimentary deposits with different soil colors and various degree of hardness are exposed in its foredune and tidal zone due to the effects of recently accelerated coastal erosion along the Ujeon Coast in Jeung-do, Shinan-gun. This study was conducted on the assumption that these sedimentary deposits were developed in different timing and environments. Thus, we can infer the geomorphic development processes of the area based on evidences like the physicochemical characteristics of each sedimentary layer. Several analysis of these sedimentary depositssuch as grain size analysis, X-ray Fluorescence Measurement (XRF), and Loss on ignition (LOI) were performed on central (Ujeon A) and southern (Ujeon B) parts of the Ujeon Coast. I found that the foredune sedimentary deposits have four stages of geomorphic development processes. In the initial stage of development, during the peak of the Last Interglacial Period (MIS 5e), basal deposits were accumulated in the low-energy environment of subtidal zones. In the second stage, during the Last Glacial Period (MIS 4~MIS 2), eolian sedimentary layers were developed by terrestrial aeolian processes by which fine materials were transported from the Yellow Sea which became a dry land exposed by lowered sea level. In the third stage, various mechanism existed for the formation of each sedimentary layer. In the region of Ujeon A, sedimentary layers were developed in the littoral zone environment dominated by marine processes during the maximum phase of transgression in the Holocene. Meanwhile, the region of Ujeon B began to form eolian sedimentary layers during MIS 2. In the last stage, thick coastal dune deposits, covered all over the Ujeon Coast. During the late Holocene (0.7~0.6 ka), terrestrial processes kept dominating the region, developing typical eolian sedimentary layers.

  • At present, due to the rapid spread of smartphones and activation of IoT, malicious codes are disseminated using SNS, or intelligent intrusions such as intelligent APT and ransomware are in progress. The damage caused by the intelligent intrusion is also becoming more consequential, threatening, and emergent than the previous intrusion. Therefore, in this paper, we propose an intelligent intrusion situation-aware reasoning system to detect transgression behavior made by such intelligent malicious code. The proposed system was used to detect and respond to various intelligent intrusions at an early stage. The anticipated system is composed of an event monitor, event manager, situation manager, response manager, and database, and through close interaction between each component, it identifies the previously recognized intrusive behavior and learns about the new invasive activities. It was detected through the function to improve the performance of the inference device. In addition, it was found that the proposed system detects and responds to intelligent intrusions through the state of detecting ransomware, which is an intelligent intrusion type.

  • Coastal lagoons(Ssangho, Gapyeongri wetland, Gunggaeho and Yeomgaeho) distribute densely around Osan-ri, Yangyang-gun. While Ssangho with the representative lagoon group in the East Coast has maintained the lagoon conditions of water surface since it was formed during the Climax of transgression, the others were formed at the swale areas of sand beach. They vary considerably in area reduction rates and position variations during the 20th century, and the causes examined can be divided into natural, human and other factors. They result in the lagoon aggradation stage by geomorphic development, reclamation due to rapid industrialization and urban development during the 20th century, and lacks of understanding on values of small coastal lagoon or errors in mapping and lags of survey techniques. Therefore, the plans for lagoon restorations should be proceeded by the individual properties of lagoons. The restorations of Ssangho are recommended preferentially and it is desirable to restore to the lagoon conditions of 1920s when the influences of human were minimum.

  • In his early poems, Wallace Stevens shows us different gestures, compared with his later poems, when he acquires reality by faculty of imagination. The former is made of ontological violence while the latter is revealed by bareness of less sensuality. However, they are the identical gestures, though from different angles, to accomplish things as they are rather than the ideas of things. In "Sunday Morning," ontological violence occurs in such epistemological couples as thought and thing, mind and world, and imagination and reality. Especially, in order to recuperate his poetic reality, Stevens undermines the traditional hierarchy between heavenly divinity and earthly divinity. In the poem, Christianity faces a critical challenge and then it is disempowered by the earthly divinity. Additionally, by disadvantaging religion, he wants to raise his poetic issue of the faculty of imagination to acquire reality. Stevens' concept of imagination is less subjective and more transcendental than Kantian one. After the ontological violence, Christian divinity and mythic gods leave ontological boundary for earthly divinity in an ambiguous way. In other words, between "Sunday" and "sunny day," the ontological conflicts haunt us throughout the poem as if the violence would happen between imagination and reality. For Stevens, both Christian divinity and mythic gods are mere obstacles to real divinity; both play a mere role of imagination before reality is revealed. Whatever reality is, imagination is always ready to draw an ontological line of reality in an ambiguous way, regardless of how long it lasts. In general, most ontological violence requires such physical remnants of conflicts as borderline, deaths, and pains which still prevail in the poem. Those ontological remnants remain to be found on earth. The sky is an abstract borderline between heaven and earth because in a sense, it belongs to both earthly landscape and heavenly sphere. Without any ontological borderline or threshold, there is no recognition of the divinity because the vitality of divinity is inflamed in continuous transgression of the other. After the final ontological conflict between heaven and earth, there remains only ambiguous borderline near the earth beside the friendlier sky.

  • In what was labeled the "nut rage" incident, the vice president of Korean Air, Hyun-Ah Cho (Heather Cho), demonstrated behavior that exemplifies corporate transgression and deviation from societal moral standards toward a flight attendant aboard a flight. Such behavior instigated the public to express negative sentiment on various social media platforms. This study investigates word-of-mouth network on YouTube in response to the crisis, patterns of co-commenting activities across selected YouTube videos, as well as public responses to the incident by employing social and semantic network analysis. A total of 512 YouTube videos featuring the crisis from December 8, 2014 through November 11, 2018, and 52,772 public comments to the videos were collected. The central videos in the network successfully attracted the public's attention and engagements. The results suggest that the video network was decentralized, with multiple videos acting as hubs in the network. The public commented on various videos instead of focusing on a few. The contents of influential videos uploaded by popular news organizations revealed not only Cho's behaviors related to the nut rage crisis but also unrelated illegal behaviors and the moral violations committed by the family members of Korean Air. The public attached derogatory remarks to Cho and her family, and the comments also addressed ethical concerns, management issues of the company, and boycott intentions. The results imply that adverse public reaction was related to the long-standing problem caused by family ownership and governance in large Korean corporations. This Korean Air scandal illustrates backlash toward a leadership breakdown by the family business conglomerate prevalent in the Korean society. This study provides insights for effective handling of similar crises.

  • As conventional oil and gas reservoirs become depleted, interests for oil sands has rapidly increased in the last decade. Oil sands are mixture of bitumen, water, and host sediments of sand and clay. Most oil sand is unconsolidated sand that is held together by bitumen. Bitumen has hydrocarbon in situ viscosity of >10,000 centipoises (cP) at reservoir condition and has API gravity between $8-14^{\circ}$. The largest oil sand deposits are in Alberta and Saskatchewan, Canada. The reverves are approximated at 1.7 trillion barrels of initial oil-in-place and 173 billion barrels of remaining established reserves. Alberta has a number of oil sands deposits which are grouped into three oil sand development areas - the Athabasca, Cold Lake, and Peace River, with the largest current bitumen production from Athabasca. Principal oil sands deposits consist of the McMurray Fm and Wabiskaw Mbr in Athabasca area, the Gething and Bluesky formations in Peace River area, and relatively thin multi-reservoir deposits of McMurray, Clearwater, and Grand Rapid formations in Cold Lake area. The reservoir sediments were deposited in the foreland basin (Western Canada Sedimentary Basin) formed by collision between the Pacific and North America plates and the subsequent thrusting movements in the Mesozoic. The deposits are underlain by basement rocks of Paleozoic carbonates with highly variable topography. The oil sands deposits were formed during the Early Cretaceous transgression which occurred along the Cretaceous Interior Seaway in North America. The oil-sands-hosting McMurray and Wabiskaw deposits in the Athabasca area consist of the lower fluvial and the upper estuarine-offshore sediments, reflecting the broad and overall transgression. The deposits are characterized by facies heterogeneity of channelized reservoir sands and non-reservoir muds. Main reservoir bodies of the McMurray Formation are fluvial and estuarine channel-point bar complexes which are interbedded with fine-grained deposits formed in floodplain, tidal flat, and estuarine bay. The Wabiskaw deposits (basal member of the Clearwater Formation) commonly comprise sheet-shaped offshore muds and sands, but occasionally show deep-incision into the McMurray deposits, forming channelized reservoir sand bodies of oil sands. In Canada, bitumen of oil sands deposits is produced by surface mining or in-situ thermal recovery processes. Bitumen sands recovered by surface mining are changed into synthetic crude oil through extraction and upgrading processes. On the other hand, bitumen produced by in-situ thermal recovery is transported to refinery only through bitumen blending process. The in-situ thermal recovery technology is represented by Steam-Assisted Gravity Drainage and Cyclic Steam Stimulation. These technologies are based on steam injection into bitumen sand reservoirs for increase in reservoir in-situ temperature and in bitumen mobility. In oil sands reservoirs, efficiency for steam propagation is controlled mainly by reservoir geology. Accordingly, understanding of geological factors and characteristics of oil sands reservoir deposits is prerequisite for well-designed development planning and effective bitumen production. As significant geological factors and characteristics in oil sands reservoir deposits, this study suggests (1) pay of bitumen sands and connectivity, (2) bitumen content and saturation, (3) geologic structure, (4) distribution of mud baffles and plugs, (5) thickness and lateral continuity of mud interbeds, (6) distribution of water-saturated sands, (7) distribution of gas-saturated sands, (8) direction of lateral accretion of point bar, (9) distribution of diagenetic layers and nodules, and (10) texture and fabric change within reservoir sand body.
